We had managed to setup and test the Continous Recovery of a secondary machine. What we need to achieve is for it to recover as primary in the event that primary fails. We know that we can use the "trigger_file" setting to fail over. However we understand that sometimes network connection can be intermittent and other factors which doesn't actually create a real "primary down" situation. So for those kind of scenarios can we set something in the configuration files like a time interval to wait before to fail-over. Has PostgreSQL this feature?
